The Alfa Romeo MiTo GTA Concept is a prototype progresses sportier version of this model (in series will occur in 2009). "GTA" (Gran Turismo Lightened) stands defining variants of Alfa Romeo sports. These models try to provide good power to weight ratio thanks to a content weight and powerful engines. To provide an adjusted weight, the body of the Alfa Romeo MiTo GTA Concept incorporates carbon fiber tailgate spoiler, roof tops and mirrors. In addition, the brake system, suspension and chassis parts are made of aluminum. According to Alfa Romeo, the bodywork has been changed profoundly and optimizing many structural elements and reinforcement.
240 hp turbo engine
On the propeller, little information is disclosed. It is a proponent of direct fuel injection with dual continuous variable valve timing and turbocharger. Has a displacement of 1,750 cc and maximum power of 240 hp. According to Alfa Romeo, this engine offers a performance equivalent to a 3000 cc engine, while fuel consumption and CO2 emission levels are maintained at an average 4-cylinder engines.
This engine has two continuous phase variable camshafts on the intake and discharge phases to optimize any scheme, engine load, while minimizing the consumption and emissions.
The turbocharger is connected to a discharge manifold type "Pulse Converter that takes full advantage of the discharge pressure waves to increase the torque at low engine speeds. Both the manifold and the turbine are made of steel Microfund to reach very high operating temperatures (up to 1020 º C), very important to reduce consumption during operation on medium / high constants.
The production model will be for the king absolute power of the category, beating rivals such as the MINI John Cooper Works, SEAT Ibiza Cupra, Clio Renault Sport, and Opel Corsa OPC.
The study of aerodynamics has had a decisive influence. The drag coefficient is the best in the whole range (Alfa Romeo unveils not). With this improved aerodynamics increases the maximum speed is achieved more stability at high speeds, reduces consumption and efficient management of flows of air in the front (to cool the engine compartment).
In particular, the front is characterized by wide air intakes needed to "do breathe" the engine, plus the new styling of the classic Alfa Romeo grille, the shield placed on the hood and the new bumper (the hood includes baffle Gap). The headlights offer a new treatment that darken to ensure the absence of reflexes (this is obtained thanks to a new paint from the surface of the parable of the bi-xenon headlights). In side view highlights new ventilation devices for cooling the engine - which recalls the 8C Competizione - which fit together in the direction indicators, while the many wind tunnel tests have "captured" to optimize aerodynamic skirts air flows through the sides and rear of the vehicle.
Rear diffuser
At the rear, the bumper has an air extractor needed to increase the aerodynamic lift, the center of which stands the dual exhaust pipes of large dimensions. The tailgate is made entirely of carbon fiber and features an integrated spoiler with a more extended wing on the top and side.
The underbody has been optimized for gain in aerodynamic efficiency. The rear floor is flat and the muffler exhaust system is fully integrated cross in the diffuser. Alfa Romeo has given special attention in defining all accessories and components mounted under the floor, while adequate protections carry aerodynamic airflow to obtain a permit downforce at high speeds.
The Alfa Romeo MiTo GTA Concept equips a fluoformado aluminum wheels and assembly of 19 ", characterized by a design made to allow adequate cooling of the brakes. The tires are made especially by Pirelli for this model.
To present the Concept GTA MiTo, Alfa Romeo has chosen to paint the body a white "Tritecno" a shade that allows much better ways to stress the body and the contrast remarcda textures of the pieces in special materials.
